Omron has introduced a range of compact, industrial, solid state relays (SSRs) offering a prolonged life and minimal risk of failure.
The new G3PE industrial solid state relay, the successor to Omron’s popular G3PB series of compact, slim-profile solid state relays, offers improved endurance and reliability characteristics. Key to its robustness is its increased resistance to surge voltages, owing to an original surge-pass circuit that gives it enhanced surge endurance and protects it against voltages in excess of 30 kV.
The basis for the G3PE’s performance is the DBC (direct bonded copper) substrate, which yields a super-thin base, eliminating the thick, heavy copper bases achieved previously. This not only results in fewer layers and enhanced electrical insulation, it also achieves lower thermal resistance values and because the expansion coefficient matches silicon, much better power cycling capabilities (up to 50 000 cycles).
The G3PE is suitable for a wide range of applications, especially those in the areas of moulding, packaging and food processing, where reliability is essential for process continuity and therefore productivity. The availability of non zero-cross functional types also makes it ideal for applications with high inrush current, such as lamp (halogen) heater control, in combination with the EJ1 temperature controller and the G3ZA multi point power controller. Enhanced safety features include a terminal cover design offering greater finger protection. The G3PE is available in a wide range of ratings with screw or DIN-rail mounting.
